Annabelle measured and recorded the amount of rainfall for 9 days in a row. Her results are shown below. 3/10in., 1/5in.,1/10in.

Answer:

Therefore, the average amount of rainfall per day for the 8-day period is 0.2375in.

Step-by-step explanation:

We know that Annabelle measured and recorded the amount of rainfall for 9 days in a row. Her results are shown below. 3/10in., 1/5in.,1/10in., 3/10in., 2/5in., 1/5in., 1/5in., 1:5in.

We have 8 values given. So we will calculate the average value in 8 days.

We have

3/10+1/5+1/10+3/10+2/5+1/5+1/5+1/5=19/10

we get

$\frac{19/10}{8}=0.2375$

Therefore, the average amount of rainfall per day for the 8-day period is 0.2375in.

What is the value of this expression when a = 2 and b = -3?

Serhud [2]

Answer:

Step-by-step explanation:

(a^3 - b^3) / 5

Let a=2 and b = -3

Do the exponents inside the parentheses

(2^3 - (-3)^3) / 5

Then add

(8 - (-27))/5

Subtracting a negative is like adding

(8+27)/5

( 35)/5

What is the area of the obtuse triangle given below

expeople1 [14]

Answer:

Option D 9 sq units

Step-by-step explanation:

we know that

The area of a triangle is equal to

$A=\frac{1}{2}(b)(h)$

where

b is the base

h is the height

In this problem we have

$b=9\ units\\h=2\ units$

substitute in the formula

$A=\frac{1}{2}(9)(2)$

$A=9\ units^2$
